1) a program that runs all the time is a special program designed that way (e.g daemons...) It is normal that programs end once its purpose is achieved... .
2) We dont know what your script does, you havent showed it to us so I dont see how anybody can advise/help you...

What are you trying to run? Paste the contents here.

You can make a script run continuously by placing it in a continuous while or for loop and using the nohup command to run it.

Code:
while true; do
  # your code here
done

# Or using a for loop
for ((;;)); do
  # your code here
done
